Constructor Summary  

HyperbolaBranch2D(Hyperbola2D hyperbola,

static HyperbolaBranch2D 
create(Hyperbola2D hyperbola,
boolean b)
Generic constructor, using a parent Hyperbola, and a boolean to specifies if the branch is the right one (crossing the Ox axis on positive side, b true), or the left one (crossing the Oy axis on the negative side, b false).

curvature(double t)
Use formula given in http://mathworld.wolfram.com/Hyperbola.html 
double 
distance(double x,

java.util.Collection<Point2D> 
intersections(LinearShape2D line)
Returns the intersection points of the curve with the specified line. 
boolean 
isBounded()
Returns false, as an hyperbola branch is never bounded. 
boolean 
isClosed()
Return false, by definition of Hyperbola branch 
boolean 
isEmpty()
Returns false, as an hyperbola branch is never empty. 
boolean 
isInside(Point2D point)
Returns true if the point is 'inside' the domain bounded by the curve. 
boolean 
isPositiveBranch()
Returns true if this branch is the positive one, i.e. it contains the positive axis in the basis of the supporting hyperbola. 
Point2D

double 
position(Point2D point)

HyperbolaBranch2D 
reverse()
Reverses the contour, and returns an instance of SmoothContour2D. 
double 
signedDistance(double x,
double y)
